She has two babies, that is three wolves each made up of two wolves inside them: 3*2 or 2+2+2
In your equation, you say 2 (mom) + 2(kid1) + 2(kid2) which has already taken care of the number of wolves (as each has two inside them) — but then you multiply this summation by two, why?
I guess you’re splitting it uo differently but it still doesn’t make sense: you’re saying 2 (mom’s wolves) + 2 (kids) + (2 kids wolves) which covers everything because for each kid there is another wolf which you include in the 3rd 2 of your equation, but then you multiply it by two for some reason.
Even if you were counting the host body as yet another wolf that brings it to 9 not 8.
